Charles H. Sternberg (1850 - 1943) collected fossils with Edwin Drinker Cope in the 1870s. He did not associate himself with an institution but worked as a freelance and sold his specimens. At times, he worked with his three sons; together they formed a virtual dynasty of fossil collectors, probably collecting more exhibition-quality fossil vertebrates than any other team. The four Sternbergs are best known for their friendly, but vigorous, competition with Barnum Brown on the Red Deer River in Alberta in the 1910s. The Sternberg sons went on to associate themselves with various institutions, George (1883 - 1969) with Fort Hays State University, Kansas; Charles M. (1885 - 1981) with the National Museum of Canada, Ottawa; Levi (1894 - 1976) with the Royal Ontario Museum, Toronto, and produced immense collections and important research. Among specimens collected by the Sternbergs on exhibition at the Museum are the Edmontosaurus "mummy" and the Albertosaurus juvenile.
